In the second salvage step, dihydrofolate reductase (DHFR) can regenerate BH4 from BH2, a process which increases the BH4:BH2 ratio providing BH4 for coupled eNOS production of NO. In mice cell lines, DHFR inhibition or knockdown diminishes the BH4:BH2 ratio and exacerbates eNOS uncoupling (Crabtree et al. 2009).
